Chris Wilson 253a774bb0 drm/i915/execlists: Don't merely skip submission if maybe timeslicing ... Normally, we try and skip submission if ELSP[1] is filled. However, we may desire to enable timeslicing due to the queue priority, even if ELSP[1] itself does not require timeslicing. That is the queue is equal priority to ELSP[0] and higher priority then ELSP[1]. Previously, we would wait until the context switch to preempt the current ELSP[1], but with timeslicing, we want to preempt ELSP[0] and replace it with the queue. In writing the test case, it become quickly apparent that we were also suppressing the tasklet during promotion and so failing to notice when the queue started requiring timeslicing.
